WebA graph which admits a graceful labeling is called a graceful graph. A Shell graph is defined as a cycle Cnwith (n -3) chords sharing a common end point called the apex . Shell graphs are denoted as C (n, n- 3). A multiple shell is defined to be a collection of edge disjoint shells that have their apex in common.
